Southern 2x long Samsung Electronics (07747) saw afternoon losses widen to 20%; Southern 2x long SK Hynix (07709) fell nearly 30%.

SK Hynix’s ADR began trading on Nasdaq on July 10, 2026 and jumped 12.76% on its debut; Seoul-listed shares fell 14.5% the same day. The ADR rally reflects global investors paying up for scarce, direct exposure to an AI-storage leader; the Seoul selloff reflects profit-taking after prior gains and skepticism about whether HBM4 will ramp volume in Q2 as hoped. Market implication: without hard order, shipment or margin confirmation for HBM4, the AI-storage narrative premium is vulnerable to being repriced back to delivery and earnings metrics.

US demand for Mexican sugar fell to roughly 200k mt in the cycle ending September, down from over 1 mln mt in the cycle ending 2022, prompting Mexico to open talks with US authorities in November.
